Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31486382, here are decompositions:

43 + 31486339 = 31486382
79 + 31486303 = 31486382
181 + 31486201 = 31486382
349 + 31486033 = 31486382
373 + 31486009 = 31486382
409 + 31485973 = 31486382
661 + 31485721 = 31486382
1063 + 31485319 = 31486382

Showing the first eight; more decompositions exist.
